Cannot create Backup, cant choose target partition

Hello,

I installed the ATI 2011 Trail yesterday on my new system. The problem is, that I cant choose a target partition from the big dropdown list. The list seams to be empty. Also when I start ATI it always that up to 1 or 2 minutes unit I can use it. The window freezes so that I cant press any button.

My system:
Win7 - 64bit
1x SSD
2x 1TB HDD Raid 0
1x 1TB HDD

What can I do to get it running?
